ink roller arranged for movement from front to back and return acrossthe operating faces of the marker element. The plunger head and the dieassembly are provided with means whereby the entire die assembly may bereadily removed from the plunger head and replaced with another dieassembly having its cutting and marking parts of similar or entirelydifferent configuration. Frequently a plurality of such die assemblieshave been required for performing the operations upon footwear parts ofthe same design but varying as to size, and in some instances operationson footwear of a given design over a full range of sizes may be carriedout with same cutting die elements, but with a plurality of differentmarker elements, each usable for part only of the range of sizes of thework. In such cases it has heretofore been necessary to remove theentire die assembly from the machine, invert it, and with the use ofappropriate tools remove the screws or other semi-permanent devicesemployed for holding the marker die plate in position before the markerdie plate could be replaced.

The object of the present invention, generally stated, is to provide foradjustment and replacement of marker die plates in devices of thecharacter described with greater facility than has heretofore beenpossible.

Another object of the invention is to provide a die of the characterdescribed in which the marker die plate may be readily removed andreplaced without removing the entire die assembly, and withoutsubjecting the hands and fingers of the operator to danger fromaccidental operation of the machine during such removal and replacement.

A further object of the invention is to provide a die of the characterdescribed with a marker die plate capable of adjustment to variouspositions with relation to the cutting elements.

Other objects will become apparent to those skilled in the art when thefollowing description is read, in connection with the accompanyingdrawing, in which Figure 1 is a view in a front elevation of a portionof a conventional cut out and marking machine showing the die assemblyin position on the head thereof.

Figure 2 is a bottom plan view of a die assembly constructed inaccordance with the present invention.

Figure 3 is a view in front elevation of the die assembly shown inFigure 2.

Figure 4 is a detail sectional view taken along line 44 of Figure 2.

According to the present invention a cut out and marker die for use witha machine of the character described above is provided with a platecarrying the marking elements and mounted in such manner with respect tothe other parts of thedie assembly that the plate may be quick- 1yremoved and replaced or adjusted without requiring that the entire dieassembly be removed from the head of the machine. As is customary withdies of the character described, the cutting elements are mounted upon abase and the marker die plate is carried by yielding studs projectingfar enough below the base that the marker die plate may be suspendedacross and beneath the cutting edges of the cutting element. The markerdie plate is provided with apertures through which the cutting edges ofthe cutting elements may move when the plunger head of the machine hasdescended beyond the point at which the marker elements have engaged thework. According to the present invention the die plate is mounted inslidable relation to the other parts of the die assembly, so that it maybe inserted from the front when the die assembly is in position on thehead of the machine and translated rearwardly until the apertures in themarker die plate have aligned themselves with the edges of the cuttingelements. According to one aspect of the present invention, theapertures in the marker die plate are arranged for operation in any oneof a pluralityof different adjusted positions thereby effecting avariation in the displacement between the marker die parts and thecutting die parts. Locking and locating means is provided forfacilitating the alignment of the marker die plate with the cuttingelements and for locking it in position, and the present inventionparticularly contemplates that such locating and locking means heprovided with manipulative parts in such position that should themachine be accidentally actuated while the operator may have his handupon the manipulative part, his hand or fingers will not be caughtbetween the die and the work support. Likewise, the marker die plate isprovided With an extension for manipulating it, which is so disalignedwith the plane of the work support and the plane of the marker dieplate, that the operators fingers cannot be caught and mashed therebyshould the machine be accidentally operated.

Referring now to the drawings for an illustrative embodiment of thepresent invention, a cut out and marking machine of the character shownin U. S. Patent 1,990,598may comprise a frame I in which a plunger head2 is mounted for vertical reciprocation and suitably driven and clutchcontrolled in a manner familiar to those skilled in the art. Beneath theplunger head is a work support 3 which is generally provided withsuitable gaging devices and adapted to receive the work to be operatedupon. The plunger head carries a die 4 consisting of cutting elementsand marking elements and arranged to be removable from plunger head 2.Ordinarily the plunger head 2 is provided with a dovetail recess 5 forreceiving the corresponding part on the die asl sembly.

The die 4 consists of a base 6 having adovetail rail I for engagementwith the recess 5 and a lug 8 for interlocking with a suitable fasteningmeans on the plunger head 2. Carried by base 6 is a cutting die assembly9 which may be of any desired configuration and in the embodimentillustrated in the drawings consists of two series of three triangularcutting edges III, II, I2, I3, I4 and I5 and one series of twotriangular cutting edges I6 and I1. Such cutting elements are ordinarilypermanently mounted on base 6. Downwardly depending from base 6 is aplurality of yieldable studs I8 suitably arranged as, for example,telescopically and provided with coiled springs tending to maintain theparts in extended position as shown. Carried by the lower ends of studsI8 is a frame I9 which is arranged, when in normal position, at aboutthe same elevation as the cutting edges of the various cutting elements.

At opposite sides of frame I9 a track-way is provided for the receptionof a marker die plate 20. Such a track-way may be formed as shown indetail in Figure 4 by securing a rail 2| in spaced relation to frame I9.The overhanging relation being provided by means of a spacer 22 ofsufliciently greater vertical dimension than that of plate 29 to permiteasy sliding movement of the plate 29 in the channel thus providedbetween rail 2| and frame IS.

The die plate 20 may be provided with marking elements 23 of anysuitable or desired configuration.

Mounted upon the upper surface of frame I9 is a spring detent 24, havinga manipulative part 25 and a tip 26. The tip 26 may engage within asuitably positioned hole such as 21, 28 or 29 in the plate 26 forproperly locating the marker die plate with reference to the otherelements of the die.

In the embodiment shown in the drawing the marker die plate 20 isprovided with apertures 30, 3| and 32 arranged to permit passage of thecutting edges of the die elements. In the'embodiment shown in thedrawing the apertures 36, 3| and 32 are enlarged so as to accommodatethe cutting edges of the die elements in a variety of adjustedpositions. In the position shown in full lines in Figure 2 the markerdie plate 20 is so arranged that tip 26 of the locating and lookingdetent 24 is engaged in hole 21, but it will be apparent that when it isdesired to use the die assembly upon a lot of work which requires agreater displacement between the edges of marker 23 and the cuttingedges of the cutting elements, the marker die plate may be slidforwardly, so that tip 26 engages hole 28 or 29. For example, when thetip 26 is seated in hole 29 the marker die plate is positioned as shownin broken lines in Figure 2.

An extension 33 is provided on the forward edge of marker die plate 20-and bent upwardly at an angle so that when the die is depressed intoengagement with the work support 3, the terminus of extension 33 cannotbe in engagement with the die plate, and consequently although anoperator may have his fingers on extension 33 when the machine waaccidentally operated, they could not be caught and mashed between thework support and the -die. The extension 33 may also be provided with aknurled part 34 to facilitate gripping and manipulation of the die plate20.

In operation of the device when it is desired to remove and replace dieplate 20 the operator engages the manipulative part 25 of detent 24 andraises it to disengage pin 26 with the corresponding hole in die plate20'. While the detent 24 is thus raised the operator may with his otherhand engage extension 33 and extract die plate 26 by drawing itforwardly. Another die plate may then be inserted in its stead byplacing the extremities of the die plate in the channels providedbetween rails 2| and frame I9 at opposite sides of the assembly. Theplate is then moved rearwardly until pin 26 engages one of holes 21, 28or 29 which indicates to the operator that the marker die plate isproperly aligned with its apertures located to accommodate passage ofthe cutting die elements. Suitable indicia may be provided opposite theholes 21, 28 and 29 to apprize the operator as to the range of sizeswhich may be operated upon in each such position, and accordingly theoperator will adjust the position of the plate until the pin 26 engagesthe appropriate hole.

From the foregoing description, it should be apparent that the inventionaccom lishes its objects and provides a cut out and marker die havingquickly removable and replaceable marker die elements withoutnecessitating. the removal of the complete die assembly from themachine,

' and further that such removal and replacement may be accomplishedwithout necessitating that the operator place his hands or fingers inpositions where they may be subject to be mashed through accidentaloperation of the machine. The arrangement of the present invention lendsitself to increased versatility of marker elements by provision for theuse thereof in a variety of adjusted positions.
